Hi Madalina, unfortunately no one is going to be to tune your servers through email. Your issue is that AIX and TSM all have the default settings. I don't think anyone should be surprised that is not optimal.
What you need to do is establish a perf and tuning methodology. Establish a base line - which you might have already done. Make a change. Run the same test and see what affect it had on the performance. There are so many different combinations of tuning parameters that it would be rare to find some one with an environment exactly like yours. Find a copy of the AIX 5 perf and tuning guide and a TSM perf and tuning guide.

The OS is in the state it came preinstalled , no patch added (right now i cannot look for the ML), no params changed . Same to TSM ...only installed on TSM I hope u can recommend some patches or tuning for parameters (in OS or in TSM) in order to improve the performances.
